fix(tui): show the provisional ~ in the all-targets count scope

[raphaelvigee]

The ~ on the header denominator means "this total is not final". The matched scope has always painted it while the matcher streams; the all scope never did — so pressing a toggled from 1 / ~800 done to 1 / 42 done, and that second number reads as a settled total it is not.

The all-scope total is if anything more provisional than the matched one: it grows both while the matcher streams and as running targets pull in deps that have not been observed yet. So it now carries the ~ while either can still happen, and drops it once the matcher has resolved and nothing is in flight.

A walk that never completed (failed or cancelled) never emits complete: true, so the ~ persists into the final summary — deliberately, and matching what the matched scope already does: the set never became final, so the denominator never became exact.

Tests

• all_scope_total_carries_a_tilde_until_nothing_more_can_arrive — streaming → in-flight → settled.
• all_scope_tilde_survives_a_walk_that_never_completed — both scopes keep the ~ after a failed walk.
• all_scope_has_no_tilde_when_no_matched_event_ever_arrives — entry points that emit no Matched still settle to an exact total.
• count_scope_toggles_done_and_cached_between_matched_and_all updated for the new all-scope rendering.

O(1) on the frame path, as before — two emptiness checks and two bools, no set walk.
